A few degrees can make a big difference when it comes to food storage. Foods can go bad if they get too warm. But for many of the world’s poor, finding a good way to keep food cool is difficult. Refrigerators are costly and they need electricity.
Yet spoiled food not only creates health risks but also economic losses. Farmers lose money when they have to throw away products that they cannot sell quickly.
But in nineteen ninety-five a teacher in northern Nigeria named Mohammed Bah Abba found a solution. He developed the “Pot-in-Pot Preservation/Cooling System.” It uses two round containers made of clay. A smaller pot is placed inside a larger one. The space between the two pots is filled with wet sand. The inner pot can be filled with fruit, vegetables or drinks. A wet cloth covers the whole cooling system.
Food stored in the smaller pot is kept from spoiling through a simple evaporation(蒸发) process. Water in the sand between the two pots evaporates through the surface of the larger pot, where drier outside air is moving.
The evaporation process creates a drop in temperature of several degrees. This cools the inner pot and helps keep food safe from harmful bacteria. Some foods can be kept fresh this way for several weeks.
People throughout Nigeria began using the invention. And it became popular with farmers in other African countries. Mohammed Bah Abba personally financed the first five thousand pot-in-pot systems for his own community and five villages nearby.
In two thousand, the Rolex Watch Company of Switzerland honored him with the Rolex Award for Enterprise. This award recognizes people trying to develop projects aimed at improving human knowledge and well-being. A committee considers projects in science and medicine, technology, exploration and discovery, the environment and cultural history. Winners receive financial assistance to help develop and extend their projects.

It has been more than twenty years since pioneering British computer programmer, Sir Tim Berners Lee, created the World Wide Web. But could he have ever imagined how much the web would change our lives? And would he approve of how some British students are taking advantage of his invention?
Universities and exam boards around the UK are becoming increasingly concerned with the rising number of cases of plagiarism, many of which are facilitated (助长) by the Internet access.
In the UK most school and university students complete coursework throughout the academic year which contributes toward their final mark. In many cases coursework makes up the main part of the qualification. Since coursework is completed in the students’ own time it cannot be monitored by teachers in the same way as an exam.
Derec Stockley, director of examinations in the UK, explains, “Plagiarism affects coursework more than anything else, and in the cases that come to our attention, more and more are linked to the Internet.”
At a university level recent reports suggest that plagiarism has evolved from separate cases of individual cheating to systematic and even commercial operation. Students can now pay for bespoke essays to be written for them by experts.
It is estimated that the market in online plagiarism is now worth 200 million pounds a year. Every month more and more websites offering to write student’s essays for them appear on the Internet.
Barclay Littlewood, owner of Degree Essays UK employs 3,500 specialist writers and charges between 120 pounds and 4,000 pounds per essay. However, Mr. Littlewood refutes the accusation that he is helping students to cheat.
51.What dose the underlined word “plagiarism” in Paragrha 2 mean in the passage?

Like all animal species, plant species must spread their offspring to suitable areas where they can grow and pass on their parents’ genes. Young animals generally spread by walking or flying. Because plants don’t have that ability, they must somehow hitchhike(搭车). Some plant seeds scatter by blowing in the wind or floating on water. Many other plant species, though, trick an animal into carrying their seeds. How do they do this? They enclose the seeds within a tasty fruit and advertise the fruit’s ripeness by its colour or smell. The hungry animal collects and swallows the fruit, walks or flies off, and later spits out the seeds somewhere far from its parent tree. Seeds can thereby be carried for thousands of miles. It may surprise you to learn that plant seeds can resist digestion. In fact, some seeds actually require passage through an animal’s body before they can grow.
Wild strawberries offer a good example of hitchhiking tactics. When strawberry seeds are still young and not yet ready to be planted, the surrounding fruit is green, sour and hard. When the seeds finally mature, the berries turn red, sweet, and tender. The change in the berries’ colour serves as a signal to birds which then eat the strawberries, fly off, and eventually spit out the seeds.
Naturally, strawberry plants didn’t set out with a conscious intention of attracting birds only when their seeds were ready to be dispersed. Nor did birds set out with the intent of planting strawberries. Rather, strawberry plants evolved through natural selection. The sweeter and redder the final strawberry, the more birds spread its ripe seeds; the greener and more sour the young strawberry, the fewer birds destroyed the seeds by eating berries before the seeds were ready.
46.What does the underlined word “dispersed” in the third paragraph mean?
A.spreadB.eaten
C.born D.planted
47.For plants, which of the following is NOT a way of spreading their offspring to suitable areas?
A.Hitchhiking. B.Blowing in the wind.
C.Floating on water.D.Tracking an animal.
48.Which strategy does the example of wild strawberries describe?
A.The conscious intent of attracting birds. B.Spreading by walking.
C.Spreading by flying.D.The strategy of taking a lift.
49.Why does the author describe how strawberry seeds are spread?
A.To show plants are good at adapting to the environment. .
B.To show strawberry’s special way.
C.To show the plant has different ways of spreading seeds.
D.To show the mystery of plant.
50.What’s the passage mainly about?
A.How animals disperse offspring.B.How plants disperse their offspring.
C.Plant evolution.D.Plants’ hitchhiking on animals.

Like other student athletes, Ray Ray McElrathbey deals with schoolwork, practice and games. But after a long day of studying and working out on the football field, the Clemson University player can’t relax with friends. Ray Ray has to make sure his 11-year-old brother, Fahmarr, gets a good dinner, does his homework and goes to bed.
Since taking responsibility for Fahmarr this August, “I’ve aged dramatically, ” said Ray Ray. “I can’t be running around at all hours, making 19-year-old decisions.” Ray Ray has temporary custody (监护权) of Fahamrr. Their mother struggles with drug addiction, and they are not in touch with their dad. Ray Ray didn’t want to see his brother go into foster care(收养), where both of them have spent time. The brothers now live together in an apartment near the campus in Clemson, South Carolina.
Clemson Tigers fans aren’t the only people rooting for Ray Ray. Sports Illustrated, ESPN and ABC News have featured the story of the brothers. They have received praise and many offers of help, but Ray Ray attends the university and arrange their life on a scholarship. Under the rules, he can’t accept money or gifts. Coaches’ family members can’t even give Fahmarr a ride home from school.
This changed a few weeks ago, when the National Collegiate Athletic Association allowed Clemson to set up a trust fund for Fahmarr. It will help provide for his basic needs, including food and clothing. However, the brothers can give each other something that all the money in the world can’t buy. Ray Ray says he hopes to instill in Fahmarr qualities of “strength and intelligence”. He says having his brother around is “a great thing, knowing he will grow up right.”

An earthquake happens when two plates(板块) rub (碰撞) together. The earth plates travel in different directions and at different speeds. If one plate is slowly forced underneath the other, pressure builds up until the plates break apart. This process causes the ground to move. It is an earthquake. In other words, earth-quakes are the shaking of the earth’s surface caused by the earth’s rocky outer layer as a result of the energy stored within the earth. The strain within the rocks is suddenly released (释放).
The damage an earthquake causes depends on where it is and the time it is happening. If an unpopulated region is struck, there will be low loss of life or property. If it hits a large city, there may be many in-juries and much destruction. Many of the areas at risk are largely populated now. Major earthquakes hitting those areas today could produce terrible damage.
Actually, there are several million small earth-quakes every year. Large earthquakes such as the 1964 Alaskan quake that measured 9.2 on the Richter scale, cause millions of dollars in damage. In the last 500 years, millions of people have been killed by earth-quakes around the world — including 240,000 in the 1976 Tangshan earthquake in China.
A 60-second or less earthquake can cause devastation that continues for years after the first tremor (小震). In 1972, a series of severe earthquakes struck Managua, Nicaragua. Fifteen years later, the city still looked the way it had a week after the earthquake hit, because the country did not have the necessary money to rebuild it.
The shaking of the earth is sometimes not the greatest disaster. It is in the ensuing fires and floods that often the greatest damage occurs. In the 1906 earthquake, it was the fires caused after it that did the majority of the damage. An earthquake can also destroy dams high above a city or valleys, causing floods to sweep down and sweep away everything in their path.
61.Which of the following is the main idea of the first paragraph?
A. An earthquake comes from inside the earth.
B. The earth has great energy in storage.
C. How the earth plates move.
D. How an earthquake happens.
62.How many examples are used in the passage to show the damage and destruction earthquakes cause?
A. Three. B. Four. C. Five. D. Six.
63. Which of the following is mentioned to show that an earthquake can kill too many people?
A. The 1964 Alaskan quake. B. The 1976 Tangshan earthquake.
C. The 1972 Managua earthquake. D. The 1906 earthquake.
64. The underlined word “ensuing” in the last paragraph probably means ______.
A. causing too much heat and great damage
B. causing many injuries and much destruction
C. happening as a result of another event
D. happening suddenly and unexpectedly
65. By giving the example in Paragraph 4, the author wants to show that ______.
A. an earthquake doesn’t last long B. the damage can last long
C. people in Managua suffered too much D. Nicaragua is still a poor country


Japanese students work very hard but many are unhappy.They feel heavy pressures from their parents to do well in school.Most students are always being told by their parents to study harder so that they can have a wonderful life.Though this may be good ideas for those very bright students,it can have very bad results for many students who are not quick enough at learning.
Unfortunately,a number of students killed themselves.Others are after comfort in using drugs.Some do bad things with trouble-makers and turn to crime.Many of them have tried very hard at school but have failed in the exams and have disappointed their parents.Such students feel that they are less important and leave school before they have finished their study.
It is surprising that though most Japanese parents are worried about their children, they do not help them in any way.Many parents feel that they are not able to help their children and that it is the teachers' work to help their children.To make matters worse, a lot of parents send their children to special school called juku-cram schools.These schools are open during the evening and on weekends, and their only purpose is to prepare students to pass exams, they do not try to educate students in any real sense of the real world. It thus comes as a shock to realize that almost three quarters of the junior or high school population attend these cram schools.
Ordinary Japanese schools usually have rules about everything from the students' hair to their clothes and things in their school bag.Child psychologists now think that such strict rules often lead to a feeling of being unsafe and being unable to fit into society.They regard the rules as being harmful to the development of each student.They believe that no sense of moral values is developed and that students are given neither guidance nor training in becoming good citizens.
